Abstract

Sensitive end-column amperometric detection has been successfully coupled to capillary electrophoresis for chiral separation of promethazine, with a carbon fiber microdisk electrode as working electrode. Baseline separation and sensitive detection were achieved under optimum conditions: 0.030 M Na2HPO4 and 0.015 M citric acid at pH = 2.50, 1.0 mM beta -CD, 10 kV separation voltage, and detection potential 1.10 V (vs Ag/AgCl). The numbers of theoretical plates were higher than 700000, and the detection limit was 5 x 10(-8) M. On-line treatment of the electrode has also been studied and discussed.
